Don\'t forget Ursula K LeGuine\'s Earthsea trilogy and its\' sequel.
Edit: You have to call Tehana\'s Story a sequel to trilogy as it was written 15 to 20 years later than the others in her mature style and shows her strong feminist beliefs. Fortunately it does not suffer from this, unlike most of her modern work.
I have nothing against Feminist scifi and fantasy, I just think in a lot of cases the politics gets in the way of the story - instead of driving it, or being the background to it.
